As you see, this porcelain bowl is not in pristine condition. An old glued repair has given up and two lumps fell off. The bowl was made in Lowestoft, probably in the 1770s, so rather than throw it away I decided a crude epoxy job would do.
First stick the two escaped bits together.
Then stick them into the bowl like so.
When the glue has dried the bowl goes onto a shelf.
Why bother though? With that amount of damage, even a 250 year old porcelain bowl is worth very little. Because of its condition I only paid a couple of quid for it about twenty years ago.
A professional restorer would have stuck it back together in such a way that only a very close inspection would reveal the damage, but the cost wouldn't be worthwhile. As far as collectors are concerned it is still a badly damaged and not particularly rare bowl.
Yet I could never have thrown it away. It's nothing to do with the value because it has none to speak of, but the age of the thing seems to give it some kind of cachet. The cachet won't last though. One day a descendant is bound to wonder what on earth it is and throw it out.
